Why Choose the Pizzato NG 2D5D511A-F31 Safety Switch with Lock?
The Pizzato NG 2D5D511A-F31 is an NG series RFID safety switch with guard locking and high-coded actuator designed for reliable monitoring and retention of movable guards on industrial machinery. It combines non-contact RFID actuator detection, electronic safety monitoring and a high-strength mechanical locking system for controlled access to hazardous machine areas.
This configuration uses Pizzato's D working principle, meaning the actuator is locked when the electromagnet is de-energised. The switch has a robust metal housing with three M20 × 1.5 threaded conduit entries, an orientable head with key-operated auxiliary release and environmental protection to IP67 according to EN 60529 and IP69K according to ISO 20653.
The NG 2D5D511A-F31 is supplied complete with the VN NG-F31 high-coding-level actuator. Its electronic interface provides two safety inputs, two safety outputs, separate signalling outputs for actuator insertion and locking, actuator programming/reset and an I5 EDM feedback input for external device monitoring.

Reliable RFID Guard Monitoring with EDM Feedback
The Pizzato NG platform combines RFID actuator detection with mechanical guard locking to provide dependable monitoring of protected machinery access points. On the NG 2D5D511A-F31, Mode 1 operation means the OS1 and OS2 safety outputs are active when the actuator is inserted and locked, allowing compatible safety-control equipment to verify the required guard condition.
The additional I5 EDM feedback input supports monitoring of external switching devices within the machine safety architecture. Combined with the high-coded VN NG-F31 actuator, 9,750 N holding force, auxiliary release and dedicated status outputs, the NG 2D5D511A-F31 provides a comprehensive guard-locking solution for modern automated machinery.
